' Thepriinary object of the present invention is to provide ,anv improved means for opening and vclosing easement windows, Vso

constructed as to bev operableifrom the inner side of the sill suchjis used.

Another Objectis and an interposed tscreen', vif

to provide Lan limproved closure operator of this kind, comprising but few parts, which will'serveinfa practi- .cal waythe 'purpose intended, and which may be constructedV andinstalled at a come paratively low st:

'In furtheranceofthe foregoing, I have Y provided an articulated'rod slidablethrough a bore in the stool or interior sill of a win`- dow structure, connectedf'at its -outerv end to' the sashand operable at its'inner end for swinging thesash, and manually releasableV means associatediwith theA stool forlocking y the rodinf any position Vtri/Whichv it may -beV adjusted.V This provides a substantial con-vV nec-tion for-holding the'sashv and permits'of quicli adjustment for openingand closing the window sash A v ,Y i

Other objectsand attendant advantages will be appreciated as the invention becomes better Yunderstood'by reference to thefollowfV ing description when considered in connec-V tionl withy the accompanying V,d'ra'wings,

Figure 1 'is a horizontal section through a' v easement `window structure embodying my invention 1 Fig. 2 is an enlarged vertical section `taken substantially onf the line 242 yof Fig. 1; p fligs. 3v ande are horizontalseetions vtaken oni-the line 34-.3 and-4 4, respectively,fo'lf- Fig.2;.and Y 3. i Fig. 5`is a' section'taken onl the line 5-5 of Fig. 3. l I

Myinvention is particularly'` designed for application to easement windows; and in illustrating its application I `have lin theV drawing shown briefly, a'conventional ca'sement window construction ofthe kindused for dwellings, including a screen at theV inner. side'of the-window sash. rIfhe principal parts making up the windowframeare the. stool orlinterior sill'6, uprights 7 and 8 and inner and outer facing strips 9 and-11. The

-f window sash 12 is hinged on the frame at 1 13 and swings outwardly. In the present instance, a screen -llis positioned at thein-- ner side of thecasement ."window.

yMy invention contemplatesthe provision:-

of an articulatcdfrod slid-able through ,the- Vv 60. .the latter'fa'n'd inthe further provision -V Y.

y manually releasa-ble'meanscofoperating withv stool'andconnected to the sash for swinging therodv for locking itin any, Vadjusted:position, these partsbeing associated with the stool in a novel and advantageous Vmanneras will be presently apparent. The rod. vcoinprisesj'inner Vand outersections 15 and 16` respectively-1.articulated orr `pivotally ,conf t nected togetherat 17f and slidablelengthwise 'K right `anglesto thezfa'ce of the stoohfis'the horizontal plane of the YlowerY portion of `the sash sc that'.tliexouterend ofthe -rod may vthrough aboire 18 in the stool. Thi's'boreat be connected directly tothe lower member of the sash frame. As shown in Figs. V2 and 4,' said outer endof the'rod is vpivotally connected, at19 to thesash, this connectionbeing atl present established .through the agency of a short rod section-21Tset into thesash and secured thereto by means `of apwood its bore, will b'einanifest that the sashwill be swung'on, its hinge; and inorderto proi videclearancef'or the outer. rod'section `16 i @during the'initial.` portionf;oftheiopenmg movement, the stool -is-cut awayin a horizontal planeA at one side of 'thegbore 18'A as 11idicated'by'23.` IWhen thefjoint 17 reaches anV extended position, the outer rod section-16 will', of course swing entirely free vfrom. lthe stool. .A suitable knob 24 is providedon the inneru'end 'of thefrod section 15';to [facilitate ed 'screw 22.v ABysliding thev rod lengthwise in 1 sliding theV rod baclrand forth.r` It will be i observed "that thejoint' 17; lpermits of the.

desiredv relative horizontal movement .bef tween the lrod sections 15 andl to accommodate opening and@y closing ofthe, saslinin they 'Y extended positions of the rod, and vthat when the sash is Vclosedsaid joint is disposedbef yondthe inner side, ofthe stool, :therebypermittng the inner rod'section to jbe swung instance, this inner rod section 15 will be swung substantially parallel to the facev of the stool and willk be retained in this position bya spring clip 25. It will be further observed that in this position the articulated rod construction prevents opening' of the sash to lany appreciable degree. f

For theipurpose of locking the window `to an inoperative position. i In the present 1 vleasably engaging the rod.

l side of the stool on its overhanging inner portion, and equipped with a pair of rod gripping elements 27. These elements, -respectively ulcrumed at 2801i the plate, em-

brace the rod and are adapted to bev urgedV into gripping contact with said rod by the action of concealedlexpansion springs 29 supported on-the rod. By pressing the depending ends 3l oi said gripping elements togeth'eragainst the pressure oi the springs 9.9, said-elements may be released from the rod, permitting the .saine to be freely adjust-ed.V At present, the plate 26 has 'formed therewith, an upstanding annular iange 32 litted into itlie stool and against which the outer 'ends of the springs bear. This .gripping device may beV easily set into the stool by boringthelatter from theV under side as at .33, this bore intersecting the bore as is plainly shown. lt will be obvious that yby pressing ltogether the depending ends Slofthe gripping elements, the rod will` be released so that V,it may be slid freely back and .forth .for opening and closing the window sash, and that upon releasing` said elements Athey will be instantly and .autoinatically broughtinto gripping engagement with the rod by the action of the springs for locking the .rod in Iany position to which it has vbeen adjusted.

From :the foregoing it will b-enoted thaiL the'rod coinpriseseonly an outer and an inner section pivotally connected together at lf? and'that this rod is so mounted and Y lguided that vits pivotal Aconnection `17 .it'ollows theaxial plane vot the bore 18. at all timesand is disposed at the outer edge Vof tlieistool when the sash Vis -fullopenand beyond the :innervedge of thestool Awhen the sashiisfclosed, yandthat .at all times ytherod is `lso guided .as 'to maintain this yposition of said pivotal connection whereby to hold the sash Yinany position to which it may b-e set by tlengthwise adjustment of the rod in the Vstool and when flocked in 'such position by means of 'the vlocking device.` 'In the present embodiment of my invention vthe liod'isthus guided Aby contact with the stool which it -willbe observed is shaped 'to Vprovrvide lateral support for. the inner rod secA tiony l5 .at any and all lengthwise adjusted positions thereof in the bore, and that said bore is elongated horizontally at its outer end and through a portion of its length to provide clearance for the outer rod section 16 vWhen the latter swings horizontally beore -leaving the bore. This provid-es a lsash operating meansofthe fewest possible elements which serves in .a very practical and eliiective manner tor holdingithe sash either closed .or open-ed or in any intermediate position. Y

lt is believed that the foregoing conveys 'i 70 a clear understanding loi 'th'e'objects iprefaced above, it being notedhoweveiy-thattheparticular construction -disclosed herein is 'i'or illustrative ur ose Vmerel `and that changes might be made in the construction and arrangement of parts without departing from the spirit and scope of the invention as expressed in the appendedclaim.

l claim:

ln combination with a window 'raine and a easement window sash hinged therein for swinginginovement in ope-ning andjclosing,

f the window trame having a sill which overedge of said sill in an out-or"the-way inoperative vpositionbut arranged when swung into alignment with -said outer section to be extended throughthe .aforementioned i hole inl said .sill to operate said sash, and a linger-operated holding device for releasably securing said rod to hold said Isash in any desired yposition of. adjustment, said device being received in-anfopening made in the under side of said sill at its overhanging inner edgeand extending from beneath the overhanging Vedge whereby to beconcealed from view while conveniently accessible for operation during the operation of said rod.
